Following massive agency mismanagement, I took over the strategic transformation and operational restructuring of digital marketing. The goal was to build a sustainable, data-driven marketing organization and drastically scale profitable revenue.

Measures: Regained data sovereignty by implementing Server-Side Google Tag Manager (sGTM) to bypass tracking restrictions. Built a finance dashboard with backend integration to measure actual net ROAS. Supported the shop migration to Shopware 6 with a focus on Conversion Rate Optimization (CRO).

Methodology:

Developed a full-funnel strategy across Google, Meta, Pinterest, and TikTok, activating 870,000 first-party data records. Eliminated agency dependency by recruiting and training an autonomous in-house team.

Results:

Scaled ad spend from €50,000/month to €275,000/month with maximum efficiency.

Achieved a verifiably measurable blended ROAS of 7.8.

Reduced shopping cart abandonment rate from 65% to 10% through checkout optimization.

Increased repeat purchase rate from 2% to 38% through systematic CRM activation.

Achieved full team autonomy after 8 months and annual savings of six-figure agency fees.

ROI-driven new customer acquisition and market expansion for an international gaming marketplace in a highly competitive segment.

Measures:

Radical optimization of product feeds (GTIN enrichment, SEO title optimization) to increase organic and paid visibility. Utilization of first-party data to create highly precise lookalike models for new customer acquisition.

Methodology:

Implementation of a data-driven scaling model that dynamically allocates budgets based on real-time inventory availability and contribution margins.

Results:

Establishment of a sustainable ROI of 7.1.

Significant increase in market share within the core target group through efficient budget reallocation to high-margin segments.

Validation of scalable first-party data workflows for international rollout.

Overall strategic responsibility for the performance channels of a market leader in drinking water systems (DACH region). The goal was to scale online revenue while simultaneously increasing the efficiency of ad spend.

Measures: Complete restructuring of Google Ads accounts towards a data-driven Performance Max & Search structure. Building a full-funnel setup in Meta Ads (prospecting to retargeting). Implementation of server-side tracking (GTM) to minimize data loss due to iOS14+.

Methodology: Focus on "Profit Bidding" rather than pure revenue ROAS by integrating margin data into bid management.

Results:

Increased monthly advertising revenue by +120% within 12 months.

Average ROAS of 7.9 in the main scaling campaigns.

Increased data quality by 25% through server-side tracking and improved conversion attribution.
